Once you've found a good source, make a note of it so that you can use it for your paper.
Keep a notebook or computer document that has the source's title, the page number of the important information, and a few notes about why it's important.
If you don't understand what a particular source is talking about, ask your teacher what it means so you can better understand the material.
Teachers can usually tell when students use information in their papers that they don't really understand.
This will help you move ahead efficiently as you write.
It will also help you to cite your sources correctly (more on this later).
Knowing which sources are considered good — and which ones aren't — is a skill that everyone gains with experience.
Get your teacher or librarian's help in deciding if a source is credible.
Even if you've read countless books, websites, and journals, and have all your notes prepared, it's normal to struggle with exactly how to get started on the actual writing. And you can always revise the actual writing later — the important thing is getting your ideas down on paper.
(You may have learned this approach in elementary school as writing a "web.") After your ideas are on paper, you can start outlining them.
